The Wii--which retails for $250--launches tonight across North America. And on eBay, one can buy the rights to one of the pre-ordered consoles for roughly $500.

Now, that's double the retail cost. Which, extrapolated to the PS3's top-end $600 price tag equates to $1,200. And in fact, PS3s are now selling on eBay for just a little bit more than that.

But pure numbers show that the buzz--at least in terms of what people are forking over to get their hands on one of the consoles now--is still in the PS3 column.

On the other hand, that could well be because Nintendo hasn't been predicting the kind of supply shortages that Sony did. Thus, it shouldn't be too difficult to find a Wii in the coming weeks. The PS3? Not so easy.
